and how to export this app to be exe file and work ib desktop without need to open pycharm editor?
How to search for a specific code into python libraries to accomplish some specific fundtions?
your help will be highly appreciated, and thanks in advance,

Your questions are a little too broad and unspecific.

If you want some help with a specific task, you’ll want to post a link to your github repo and ask about that specific task.

I’d also suggest using some resources such as this free Tkinter book or another free book.

Building a stand-alone exe file for python is difficult. To run your program on the command line (i.e. not using pycharm) you write the following in a terminal window:

python3 your_program.py

This would be in the folder where “your_program.py” exists. [Also assumes Python 3; if you’re using Python 2, it would be “python”, not “python3”.]
